PETRONELLA EDTBAUER, OF CHICAGQ ILLLNOISQ AUTOMATIC WEIGHING APPARATUS.

The object of my invention is to dispense with theelectrical apparatus for tilting the chutes and to perform this operation by simle and comparativel inex ensive mechanlcal means, that are ess liable to get out of order, and are at all times capable of performing the functions assigned to them. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

Inthe drawings :Figure 1 is a vertical longitudinal section through the weighing apparatus to which my improvements are applied. Fig. 2 is a front vlew of the same with the scales removed. Fig. 3 is a. fragmentary view of my invention, drawn to a larger scale, showing in perspective the mechanism actuated by the scales, and employed to transmit motion to the chute supporting devices. Fig.4 is a similar view of another part of said motion transmitting mechanism. 7

In the drawings A represents the hopper of the apparatus; B thelongitudinally reciprocal inclined cut-ofl' plate or valve for the discharge opening of said hopper; C the wider and longer tiltable chute, which is divided longitudinally by a suitable artition into a narrow channel and a wider c annel, and has the lower end of its wider channel cut away; D represents the narrower shorter chute, so.

placedthat the flow from the Wider channel ing-frame E, between whose side-walls theto of the larger. chute, falls into its upper end. The longer chute C has trunnions c, 0, projecting laterally from its side, that are journaled in hearings in the sides, of the supportrincipal parts of my invention are assembled. The part or portion of chute G which is uppermost, when the contents of the hopper are being directed. into the scales', 1s suported by an arm f secured to and pro ecting rom its upper end, which latter has its extremity resting on a shoulder 2 of an arm 3 Specification of Letters Patent.

projecting upwards from a short rock-shaft 4 ournaled in the adjacent side-wall of the supporting-frame. of the supporting-framea horizontal arm 5 projects forward a suitable distance from the opposite end of this rock-shaft, and the forwardend of this arm 5 is engaged bya vertically' disposed connecting-rod 6, as will hereinafter be more fully explai nedr I The "upper end of the smaller chute D is similarly supported by means ofan arm 7 extending from its upper end, the extremity of which is adapted to rest on the shoulder 8' of an arm 9 projecting upwards from a suitable rock-shaft 10, which latter is likewise journaled in the side-walls of the sup ortingframe, and outside of said side-wal s has a horizontal arm 11 projecting forwardfrom its opposite end, the forward extremity of which is engaged by a vertically disposed connecting-rod" 12, as will hereinafter more fully appear. a

When the upper ends of'both chutes C and D are in the position just described, they direct the flow of the commodity from the hopper, over an inclined shed 13 into the scoop or pan 14 of the scales 15, but when the support under the upper heavier ends ofthese chutes is withdrawn, and they tilt backwards, they discharge the flow from the hopper into a funnel. F, below which any suitable receptaclefor catching the excess of the hopper is placed. I

My invention is concerned only with the means for supporting the upper ends of the chutes. I All the remainder of the mechanism is constructed and operates, the same as the corresponding parts, described and illustrated in the aforesaid Letters Patent of the United States granted to me June18y1907,

No. 857,164, and I make no claim specifically to-the same. The lower end of the'connecting-rod 6 is ivotally connected to the endof a horizonta ly disposed rock-bar 20, whose opposite shorter end is suitably weighted, and has its extremity normally resting upon bracket 17 projecting laterally from the lower end of the vertical column 18 forming the support for the adjacent platform of the scales 15. The lowerendof the connecting- .Outside, of the side-walls rod 12 is pivotally connected with the lon er end of a rock-bar 16, which is placed para lel to rock-bar 20, and has'its opposite suitably weighted and shorter arm also normall 'resting upon bracket 17 of the scales. 1 'The onger arm of rock-bar 16 is longer than the correspondingarm of rock-bar 20, consequently, when the platform of the scales to which bracket l7vis attached moves downwards under the weight of the commodity receivedby the scoop thereof, rod 12 Wlll have a greater reciprocal movement than rod 6, and will actuate arm 9 through the medium .of the horizontal arm 11 so as to withdraw its su port 8 from under the upper end of t e smaller chute D and cause the same, by reason of its gravity, to tilt backwards and discharge its contents into the funnel F 'of the apparatus. This action of 'chute D cuts off t e flow of the commodity into the scoo of the scales, and the scoop will rise slig tly until the flow of the commodity received from the n' rrower channel of chute C completes the weight, whereupon the scoop moves to the limit of its downward movement and imparts movement to the rock-bar 16 which moves the connecting-rod 6 upward sufficient to move arm 3 out from under the upper horizontal end of the larger chute C.

In order to remove the pressure of the weighted end of the rock-bars 16 and 20 from the bracket 17 of the scales, and permit the return of the scoo or pan of'the scales to its original position} provide the trunnions of chute C, preferably on the end extending beyond its bearings with a concave wheel 21 and secure to and extend partially around the. circumference of this wheel,- a chain or cord 22, which, preferably, extends forward around a concave sheave 23 and then downwards to a horizontally dis osed rock-bar 27 to one end of which the ower end -of the chain is secured. This rock-bar 24 is, preferably, arranged at right a'ngles'to rock-bar 16 and its opposite end laps over the longer end of rock bar 16. In like manner the rock-bar supporting the smaller chute D is provided wlt a concave-wheel 25- and one end of a 'chain 26 extends partially around the same and from thence depends downand its lower end secured to one end of-a rock-bar 27". Rock-bar 2 7 is, preferably, placed parallel to rock-bar 24, and it is, to ether with the latter, adapted ,to restore roc -bars to their normal positionsthat is, the posi-.

tion they should be in" when the scoop of the scales is'empty', by reason of the winding of the up er ends, of said ch'ains u on the concave w heels where the chutes ti t rearwards. When this is done the Wei hted ends of said rock-bars 16 and 2-0-are li ted from" bracket 17 and the opposition to the restoration of the scales to their original positionremoved.
